EVALUATING SOURCES
Begin by reading overviews of your topic.
Always think critically about every
source used. A research paper
can be no better than the sources used. Consider the following questions:
Is an electronic
source as good as a paper source?
Determine if the webpage provides equal or better information in terms
of accuracy, authority, objectivity, and currency as published literature or
journal articles.
Are there advantages
to using a paper source? Paper sources
have been screened by publishers and editors knowledgeable in that field. Their reputation and their business depend
on selecting worthy material to publish. Material on the Internet is not
screened.
Have you compared websites
or paper sources to other sources if there is any doubt about content or
accuracy?
ACCURACY
Does the webpage or source list the author or the institution that published this page, and a way to make contact? If there is no author, how does the source provide its worth?
Is the
information useful, accurate, not just watered down from a better source,
repetitious, or of questionable value?
Is the
information fact or opinion?
Is the source
updated often so the information is current?
Can the
information be verified elsewhere?
For websites,
are there related links or additional sites? For paper sources, is there a
bibliography or works-cited page? What kinds of sites or sources are they:
reputable or scholarly or even real?
Does the
information have footnote documentation or other methods to reveal the source
of information? In scholarly/research
work, the credibility of most writing is proven through this
documentation. However, because
journalistic sources even from reputable newspapers may not document in the
same way, they should not be considered scholarly sources.
If information
is reproduced from another source, is it complete and genuine? Is copyright information given? It is always best to use the original source
to make sure the text is not altered or illegally reproduced.
Is the author an
expert in that field? An e-mail address
by itself does not give authority to the site.
E-mail the author and respectfully ask for more information in order to
make a critical assessment. Check the
Library of Congress for other publications by the author; Book Review Index
and Book Review Digest for reviews of books by this person or Biography
Index for biographical information; look up the author on a search engine
like Google.com. A research paper is
only as valid and credible as its sources.
Does the page
give the credentials of the author, a reputable affiliation, and domain (.edu,
.gov, .org, or .net). Look at the
header or footer to determine affiliation.
Anyone can post
a website with any information—inaccurate, biased, or misleading—on a personal
website. In a URL, a tilde ~ usually
means a personal website rather than part of the official website of an
organization. Personal websites are not bad as long as the author is credible;
however, publishing on the Internet does not guarantee credibility.
If there is no
author, who is accountable and responsible for the content?
Does the page
present accurate information objectively?
Might advertising on the page indicate bias? If the information is biased, is the bias clear (for example,
research data on effects of smoking on the website of a cigarette manufacturer)?
Does the site
provide links to other pages or cross references to other sources that present
the same topic so that the reader can evaluate the information more
critically? Does the source provide
links to opposing viewpoints to make available a balanced and unbiased view?
CURRENCY
If timeliness is
relevant, is the page current, current enough, regularly updated and are the
links maintained? For a website, the date may be important in determining
whether the author is still maintaining the page or has neglected it. Last updated usually appears at the
bottom of the webpage. Explorer File/Properties or Netscape View/Page Info may
not be reliable because these dates may be automatically updated and thus
meaningless for critically evaluating currency.
AUDIENCE
Who is the
intended audience? Information intended for middle school students would not be
useful for a college research project.
Consider
using the following to evaluate the paper source:
The preface or
introduction, in which the author explains his goals and focus in writing this
work.
Table of contents and the index for an
overview of the source and to find the specific page/s the topic appears; think
of all the different ways your topic could be indexed.
List of
references and citations that lead to related sources recommended by the
author.
The assumptions
that the author is making about the understanding of his audience, interest,
and abilities as seen in the vocabulary, sentence structure, tone, and
complexity of information.
